Flight history

Hi folks, my flight was delayed 2.5 hrs from CWL-BKK on Oct1st meaning I missed my connection at Doha and was eventually 6+hours late arrival at BKK, I need to find the details for the flight I had from Doha to BKK that arrived at approx 7pm(Bangkok time) on Oct2, I don't have the flight number, any help appreciated, thanks
